4 Claims.

This invention relates to cleaning and washing devices especially adapted for use in connection with the cleaning of drinking glasses, cups etc. etc. One object of the invention is the provision of a device of the character referred to which comprises an inner central brush and a plurality of outer brushes in close proximity and radially positioned with respect to the central brush, so that glasses of various depth and diameter or other similar articles may be moved between the said brushes and thoroughly cleaned inside and outside.

Another object of the invention is the provision of a device of this character in which a resilient rubber cup is positioned below the central brush for the purpose of preventing glass breakage.

A further object of the invention is to so mount the brushes that they may be readily replaceable.

A still further object of the invention is the provision of such a device in which all of the working parts are readily accessible,

Another object. is to produce a device of the character described in which the maximum simplicity of construction and operation is secured.

Other objects and advantages will appear as the nature of the improvements .is better understood, the invention consisting substantially in the novel arrangement and co-relation of parts herein fully described and illustrated in the accompanying drawings, wherein similar reference characters are used to describe corresponding parts throughout the several views, and then finally pointed out and specifically defined and indicated in the appended claims.

The disclosure made the basis of exemplifying the present inventive concept suggests a practical embodiment thereof, but the invention is not to be restricted to the exact details of this disclosure, and the latter, therefore, is to be understood from an illustrative, rather than a restrictive standpoint.

The inventive idea involved is capable of receiving a variety of mechanical expressions, one of which, for the purpose of illustration, is shown in the accompanying drawings, in which- Figure 1 is a side elevation of my improved glass cleaner;

Fig. 2 is a sectional View thereof taken on line 2-2 Fig. 1 with the brushes omitted;

Fig. 3 is a sectional View taken on line 3--3 Fig. 1;

Fig. 4 is a sectional view Fig. 2; V

Fig. 5 is a sectional view of the device at an taken on line 4-4 enlarged scale taken on line 5-5 Fig. 3, shown submerged in a pail of water and ready for use, and

Fig. 6 is a fragmental sectional view at an enlarged scale taken on line 6-6 Fig. 2.

Referring now to the drawings in detail, I0 indicates the base provided with a hub II in which is suitably supported the core I2 of a central brush l3 which tapers upwardly and terminates at the top thereof with a substantially reduced portion [4. Clamped to the brush core l2 somewhat below the brush I3 is a yoke l5 comprising a pair of members or bands It and I1 respectively, said bands being secured together by means of screws l8 and nuts l9 (see Figs. 2 and 4). Each of the said members is provided at one end with a bent over portion 20 and at its opposite end with a similar portion 2!. A resilient rubber cup C is mounted on the core 12 intermediate the brush l3 and yoke HE. A frame 22 surrounds the brush I3, said frame comprising two halves 23 and 22 each provided at their bottom end with oppositely extending pivot pins or extensions 25 and 2B. The pivot pins 26 fit into openings in the bent over portions 2! and the pins 25 extend into tubular members 21' which are slidably supported in the bent over portions 20 and are headed .over at 28. A spring 29 coiled about each tube 21 exerts a tension between the respective yoke portions 20 and frames 23 and 24.

The frame section 23 is provided with a lower ledge 30 and an upper ledge 3! and the frame section 24 is provided with similar ledges 32 and 33 respectively. The lower ledges are provided with holes 34 and the upper ledges with holes 35 in alinement with the upper holes, to receive the ends of the cores 36 of brushes 31, each frame section carrying three such brushes. A coiled spring 38 wound about the lower end of each brush core 36 exerts a tension between the lower frame ledges 32 and washers 39 secured to the said cores 36 below the brushes 31. The frame sections 23 and 24 are separably connected by means of springs to cooperating with pins 4| and 42 on the respective frame sections.

In practice the entire device is submerged into a pail or other receptacle 43 filled with water and the glass or other similar article Ml to be washed and cleaned is inserted mouth downwardly over the brush l3 the glass is then pushed downwardly and rotated by hand, the inner surface of the glass being cleaned by the bristles of the brush l3 and the outer surface by the bristles of the brushes 3?, the bristles of the said brushes bein sufficiently flexible to permit of the ready insertion of the glass between the brushes. I find that in rapidly pushing the glass over the brush [3 a stream of water rises in the glass and strikes the bottom thereof as indicated by the arrows A, Fig. 5. It will also be understood that when very tall glasses are washed the cup acts as a cushion to prevent the mouth edges of such glasses from coming in direct contact and striking the top of the yoke l5 and becoming smashed. By the provision of the reduced upper brush section M the inner surfaces of very small glasses may be readily cleaned.

It will also be seen that dueto the resilient mounting of the brushes 3'! they may be very readily removed and replaced, as by merely pressing down on such brushes against the tension of the springs 38 the upper end of the brush cores 36 become disengaged from the holes 35 in the upper ledges 33. Likewise by the unlatching of the springs 40 the frame sections will swing open on their pivots 25 and 26. It will further be seen that the frame sections when in open position may be removed from the supporting yoke l5 by merely pressing same against the tension of the springs 29.

said device comprising a bristle brush which is adapted to enter the interior of the article to be cleaned, the said brush having a central core, a yoke upon the said core below the brush, a two sectional frame pivotally mounted on the yoke and surrounding the brush, means for releasab-ly connecting the frame sections, and a plurality of brushes carried by the said sections about the circumference of the first mentioned brush.

2. A device for cleaning drinking glasses and the like and adapted to be immersed into water,

said device comprising a bristle brush which is adapted to enter the interior of the article to be cleaned, the said brush having a central core, a yoke upon the said core below the brush, a twosectional frame pivotally mounted on the yoke and surrounding the brush, means for releasably connecting the frame sections, and a plurality of brushes carried by the said sections about the circumference of the first mentioned brush, the said last mentioned brushes being resiliently and readily removably mounted on the frame.

3. A device for cleaning drinking glasses and similar articles comprising a base, a central conical brush having a core which is supported on the base, a yoke secured to the brush core below the brush, a longitudinally divided two sectional frame pivotally mounted on the yoke and encircling the central brush, means for releasably connecting the frame sections, and a plurality of exterior cylindrical bristle brushes mounted on the frame parallel to and encircling the central brush.

4. A device for cleaning drinking glasses and similar articles comprising a base, a central conical bristle brush having a core which is supported on the base, a yoke secured to the brush core below the brush, the said yoke having two pairs of oppositely disposed openings, a resilient rubber cup on the brush core intermediate the central brush and yoke, a longitudinally divided two sectional frame surrounding the said brush, oppositely disposed pivots at the bottom. of each frame section, the pivots on one side of the frame entering the respective openings on one side of the yoke, tubes slidably mounted in the openings on the opposite side of the yoke and slidably engaging the other frame pivots, a coiled spring Wound over each tube and exerting a tension between the yoke and tubes, means for readily releasably connecting the frame sections, and a plurality of cylindrical bristle brushes resiliently and readily removably mounted on each of the frame sections in close proximity and parallel to the central brush.
